The transaction, structured as a sale of substantially all of the assets of Chase EMS closed on June 30, 2010. All of the Chase EMS employees as well as the leased facility located in Winchester, Massachusetts have transferred to MC Assembly. Proceeds from the sale will be used for debt reduction and continued investment in the Company’s core tapes and coatings businesses.

MC Assembly ( www.mcati.com) was selected from a number of interested buyers as being most compatible with regard to geography, market, capabilities and scale.

“MC Assembly is a good fit for Chase EMS and has the resources to help the business reach its full potential,” said Peter Chase, Chase Corporation’s Chairman and CEO. “This divestiture will allow Chase Corporation to focus more of its resources on core operations. Over the last several years we have grown our Specialized Manufacturing business to be a significant supplier of protective materials used worldwide in a wide array of specialized anti-corrosion and insulating applications.

“We thank General Manager, Ron Barilone, and his entire staff for their many contributions over the past ten years and wish them personal success in the future.”

Chase Corporation, founded in 1946, is a global manufacturer of protective tapes and coatings for high reliability applications.
